Abstract: Presently described are curable compositions comprising a mixture of at least one (e.g. free-radically) polymerizable ionic liquid and at least one other ethylenically unsaturated monomer, oligomer, or polymer. The polymerizable ionic liquid is characterized as having an air to nitrogen curing exotherm ratio of at least 0.70. Also described are articles and methods of making articles from such curable compositions. A monofunctional polymerizable ionic liquid is also described comprising a non-polymerizable substituted imidazolium cationic group and a polymerizable sulfonate anion.

Abstract: Retroreflecting optical constructions are disclosed. A disclosed retroreflecting optical construction includes a retroreflecting layer that has a retroreflecting structured major surface, and an optical film that is disposed on the retroreflecting structured major surface of the retroreflecting layer. The optical film has an optical haze that is not less than about 30%. Substantial portions of each two neighboring major surfaces in the retroreflecting optical construction are in physical contact with each other.

Abstract: Presently described are curable dental compositions comprising a polymerizable ionic liquid. The polymerizable ionic liquid comprises one or more ethylenically unsaturated (e.g. free-radically polymerizable) groups. Various embodiments of curable dental compositions are described. In some embodiments, the polymerizable ionic liquid is a monofunctional polymerizable ionic liquid comprising an ethylenically unsaturated group. In other embodiments, the polymerizable ionic liquid is a multifunctional polymerizable ionic liquid comprising at least two ethylenically unsaturated groups. The curable dental compositions describe herein can be utilized as dental primers, dental adhesives, dental sealants, and dental composites. In many embodiments, the curable dental compositions further comprise an initiator such as a photoinitiator.
